Baoji Hanz Metal Material Co., Ltd. proudly offers Medical Super Elastic Nickel Titanium Flat Wire, a cutting-edge material specifically engineered for medical applications requiring superior flexibility, strength, and shape memory. Our nickel titanium alloy, often referred to as nitinol, is renowned for its superelasticity and biocompatibility, making it an ideal choice for a variety of medical devices and instruments. This material has become indispensable in modern medical technology due to its unique ability to return to its original shape after deformation.

Cardiovascular Applications

Medical super elastic nickel titanium flat wire has revolutionized cardiovascular treatments through its application in stents and guidewires. The material's superelastic properties ensure that devices such as guidewires and catheters function effectively in the human body. When used in stent manufacturing, the wire allows for the creation of devices that can be compressed into a small profile for insertion through blood vessels, then expand to their predetermined shape once in position. This characteristic is critical for minimally invasive procedures, reducing patient trauma and recovery time. Baoji Hanz Metal Material Co., Ltd.'s nitinol wire, with its 54% nickel and 46% titanium composition, provides the perfect balance of flexibility and strength required for these applications. With a tensile strength of 800pa and hardness of 30bh, our Medical super elastic nickel titanium flat wire maintains its structural integrity even under the constant strain of cardiovascular movements, ensuring long-term functionality in life-saving devices.

Orthopedic Applications

In orthopedic medicine, Medical super elastic nickel titanium flat wire has transformed treatments for bone and joint conditions. The material is extensively used in orthopaedic implants, bone plates, and bone anchors due to its biocompatibility and mechanical properties that closely mimic human bone. Our medical-grade nickel titanium flat wire offers unmatched flexibility, ensuring that it can be bent and stretched without losing its shape, ideal for intricate medical devices. This is particularly valuable in spinal stabilization devices, where the wire must provide support while allowing natural movement. The wire's shape memory effect—returning to its original shape when heated or deformed—makes it perfect for applications like bone staples that contract at body temperature to compress fracture sites. Additionally, the wire's high purity, with an impurity content of just 0.001%, meets the rigorous requirements for medical and biomedical applications, ensuring long-term stability within the human body without causing adverse reactions or deterioration, which is crucial for permanent orthopedic implants.

Dental Applications

The dental field has widely embraced Medical super elastic nickel titanium flat wire, particularly in orthodontics. Used in dental wires, it offers excellent flexibility and strength to adjust braces comfortably. The superelastic properties allow orthodontic archwires to exert constant, gentle force on teeth over extended periods, significantly improving treatment efficiency and patient comfort compared to traditional stainless steel wires. Baoji Hanz Metal Material Co., Ltd.'s nitinol wire, operating optimally at temperatures less than 80°C, is perfectly suited for the oral environment. The material's ISO9001:2015 and ISO13485:2016 certifications, along with EU CE approval, ensure that our Medical super elastic nickel titanium flat wire meets the highest standards for dental applications. Furthermore, the wire's biocompatibility means patients experience fewer allergic reactions, while its corrosion resistance in the moist environment of the mouth contributes to longer-lasting dental appliances. This combination of properties has made Medical super elastic nickel titanium flat wire the material of choice for modern orthodontic treatments.

Technical Properties and Advantages of Nickel Titanium Flat Wire

The exceptional performance of Medical super elastic nickel titanium flat wire in medical applications stems from its unique metallurgical properties. These properties result from the specific composition and processing techniques employed in its manufacture.

Superelasticity and Shape Memory

Medical super elastic nickel titanium flat wire exhibits remarkable superelastic behavior, allowing it to undergo substantial deformation and return to its original shape upon release of stress. Our wire remains elastic under stress, allowing it to return to its predetermined shape even after significant deformation. This property derives from a unique phase transformation in the material's crystal structure. Unlike conventional metals that deform plastically beyond their elastic limit, nitinol can recover from strains up to 8-10 times greater. Baoji Hanz Metal Material Co., Ltd.'s Medical super elastic nickel titanium flat wire, with its precise 54% nickel and 46% titanium content, achieves optimal superelasticity for medical applications. This characteristic is indispensable for devices like stents, which must navigate through tortuous blood vessels during placement yet maintain their designed shape once deployed. Additionally, the wire's thermal memory function ensures it performs optimally under varying temperatures, ensuring precision in medical applications. This thermal-activated shape memory effect allows devices to transform between predetermined shapes at specific transition temperatures, enabling applications where devices self-deploy when reaching body temperature.

Biocompatibility and Corrosion Resistance

Medical super elastic nickel titanium flat wire's exceptional biocompatibility makes it ideal for long-term implantation within the human body. Non-toxic and safe for use in the human body, it ensures no adverse reactions. Despite containing nickel, which can potentially cause allergic reactions, the titanium component forms a stable, passive oxide layer that effectively shields tissues from nickel ions. This natural corrosion resistance is enhanced by Baoji Hanz Metal Material Co., Ltd.'s stringent manufacturing processes, which achieve an impurity content of just 0.001%. Our ISO13485:2016 certification demonstrates our commitment to meeting medical device quality standards. The material's corrosion resistance makes it a safe and durable choice for medical applications, particularly important for devices exposed to bodily fluids over extended periods. This resistance to degradation not only ensures device longevity but also prevents the release of potentially harmful metal ions, significantly reducing the risk of inflammatory responses or rejection by the body. The combination of these properties has established Medical super elastic nickel titanium flat wire as the gold standard for implantable devices requiring both mechanical reliability and biological compatibility.

Mechanical Strength and Flexibility

The remarkable combination of strength and flexibility in Medical super elastic nickel titanium flat wire makes it uniquely suited for medical applications requiring both properties simultaneously. Despite its flexibility, this wire maintains high tensile strength, offering durability in demanding environments. With a tensile strength of 800pa, Baoji Hanz Metal Material Co., Ltd.'s nitinol wire provides robust performance while maintaining flexibility that conventional materials like stainless steel cannot match. This balance is critical for applications such as endovascular devices, where the wire must navigate complex vascular pathways without causing trauma, yet provide sufficient structural support once positioned. The temperature sensitivity of the material is engineered to activate at specific temperatures, ensuring consistency in medical procedures. This characteristic allows devices to maintain optimal mechanical properties across the range of temperatures encountered in medical applications, from storage to sterilization to use within the body. The material's combination of flexibility and kink resistance significantly reduces the risk of device failure, making Medical super elastic nickel titanium flat wire an essential component in modern minimally invasive surgical techniques.
